That you can work your butt off to make lots of money but as soon as you get paid most of it is going to go on bills...bye bye money.

That most of the people you called your friends as a child and teenager will be out of your life by the time you are a grown up.

That you can find love in the most unusual places and its best not to orchestrate it or over analyze it because it has its own rules. Love will come along and stick around when it feels like it.

That relationships and marriages aren't like fairytales. They are hard work that consists of both happy good times and hardship and struggle. If you go in it with realistic expectations and the willingness to compromise and talk things through then you have a good chance of making it last a long time.
